This code simulates an old fashioned 5x7 LED Dot Matrix Display Panel. This is a reimplementation of a C++ wxWidgets program by Christian Gr�fe (info@mcs-soft.de).

The demo app displays 7 panels to demonstrate all the options supported: 7 Color pallets, Upper/Lower case & special characters, Scrolling, Inverse video, etc. The demo uses about 35% of the CPU on my old ThinkPad and has a fair amount of flicker, it's "blit"ing a whole lot of individual LEDs. Maybe it will update smoother on a more modern PC. A single panel display should look pretty good.
